Tejo Vs Expensive Devices

Modern AI and camera technologies have dramatically advanced in the last decade

What Tejo Offers that Expensive Devices Can't

 

Virtual consultations

You can use Tejo as a virtual consultant, on your website to help guide new clients to the right service for them. This requires no work on the side of the spa, and prospective clients have a quick and easy way to connect with the spa. This can help the spa collect contact information of prospective clients as well as their biggest skin concerns. 

Scan Before Treatments

When asking clients to check in for their appointment they can also scan their skin. This will provide more up to date information about the skin.  This can help prevent any reactions and guarantee a seamless experience. 

Education on Autopilot

Its impossible to inform clients about all the products you have on offer and clients often forget what was taught. Tejo offers the ability to explain automatically to clients what products and services they should use moving forward and WHY. 

 

Understanding the Tech

algorithms that adjust for ambient lighting conditions

Lighting

subheading
Tejo uses proprietary algorithms to adjust for ambient lighting conditions.
The word Tejo comes from the Sanscript word for light because adjusting for lighting conditions is at the core of what we do.

UV and Infrared Light

subheading
UV and Infrared light is visible to modern smartphone cameras.
For older devices advancements in AI are able to detect skin issues revealed by UV and Infrared light using only the visible light spectrum[1]

UV

UV Light, used by devices like Wood Lamp are used primarily to detect [2]:

  1. Bacteria and Fungus

    We chose not to detect bacteria on the skin because of emerging research on the skin microbiome. instead we focus on signs of bad bacteria or infection.

  2. Hypopigmentation and Hyperpigmentation

    Tejo has detects both of these already, and is able to detect early signs of these, even when they are not visible

     

Infrared

Infrared Light is used to largely detect for Inflammation in a spa setting.[3] Tejo's redness score correlates directly with inflammation. [4] 

Tejo Detections For Skin

acne

Acne

Acne can be accurately and quickly assessed from a picture External studies have found accuracy ratings as high as 99.4% accuracy when detecting acne. Acne type, and severity can both be accurately assessed.[5][6]

FIne LInes and Wrinkels

Fine Lines and Wrinkels

FIne Lines and wrinkles can be captured and measured using a camera using various techniques. [7]

texture

Texture

Skin texture can be quickly and accurately assessed with a camera.[7][8]

Oil

Oil

There is fairly conclusive evidence that oily skin can be detected from a camera and that no special light or magnification is needed [7][8][9]

skin health

Skin Health

skin health is an overall assessment of how youthful and healthy the skin looks. Tejo uses an internal scale to rate images.[7]

redness

Redness/Inflammation

inflammation is assessed using visual indicators like swelling, redness, or other signs of irritation on the skin. Tejo is effective at detecting these issues even with darker skin tones.[10]

Sun Damaage

Sun damage is a composite score looking at common signs of sun damage.

Hyperpigmentation

There is strong evidence that Hyperpigmentation can be assesed with a camera. Tejo Currently uses our own unige scoring system but is  looking to implement the the MASI scoring system, soon.[11][12] Studies have found accuracy rates above 95% [13]
